The number of chromosomes in calyptra will be the same as the rhizoid, i.e, 20 because calytra is haploid in nature.

The correct answer is option 'A', which means that the number of chromosomes in the cells of the calyptra of Funaria is also 20.
Funaria is a type of moss that undergoes alternation of generations, meaning it has both a haploid and a diploid stage in its life cycle. The haploid stage is called the gametophyte, while the diploid stage is called the sporophyte.
In the gametophyte stage of Funaria, the cells are haploid, meaning they have half the number of chromosomes compared to the sporophyte stage. If the number of chromosomes in the spore sac of Funaria is 20, it means that the cells in the spore sac contain 20 chromosomes.
The calyptra is a protective cap that covers the seta (stalk) of the sporophyte stage of Funaria. It is also a part of the gametophyte stage. Since the calyptra is a part of the gametophyte and not the sporophyte, its cells will also be haploid. This means that the number of chromosomes in the cells of the calyptra will be the same as in the spore sac, which is 20.
To summarize:
- The spore sac of Funaria is a part of the sporophyte stage and contains diploid cells with 20 chromosomes.
- The calyptra of Funaria is a part of the gametophyte stage and contains haploid cells with the same number of chromosomes as the spore sac, which is 20.
Therefore, the correct answer is option 'A', which states that the number of chromosomes in the cells of the calyptra is 20.
